3 Claims. (Cl. 153-1) This application is a division of our copending application, Serial No. 686,964, filed July 29, 1946 now Patent No. 2,596,396.

This invention relates to the manufacture of electrical condensers and more particularly to an apparatus for making condenser having a foil winding enclosed in a metal can to which one foil of the condenser is electrically connected, the other foil being electrically connected to a wire extending from the can and insulated therefrom.

An object of the invention is to facilitate the attachment of a terminal clip to the condenser lead wire. To accomplish this object, the disclosed embodiment of the invention provides an intermittently operating conveyor having workholders for receiving the condensers and a punch press for forming a terminal clip and attaching it to a condenser wire when the condenser has been conveyed to the clip attaching station. The condensers to which clips are attached to their lead wires are ejected from the conveyor. The machine provides means for operating the conveyor, the press and the condenser ejector in timed relation.

Referring to Figs. 1 and 2, the machine comprises a cabinet A which supports a conveyor B carrying workholders w each for receiving a condenser C. Referring to Fig. 2, a conveyor B conveys the condensers from a machine for assembling condensers through a hopper D, the bottom of which is open so that the operator may reach in and place the condensers upon the conveyor B. As the condensers pass left in Fig. 2 and right in Fig. 3 on the conveyor B, the terminal wire Ch of the condenser is automatically connected with the testing apparatus described in our application Serial No. 686,964 now Patent No. 2,596,396. These condensers which fail to pass the tests are automatically ejected before passing to the clip attaching station. These condensers which pass the test remain on the conveyor which carries them first to a clip attaching station CS Where a terminal clip is attached to the condenser Wire. The terminal clips are made by a die operated by a punch press P. Then the condensers pass to a welding station WS where the clip is welded to the terminal wire by an electric welder W. At the right end of the cabinet, the condensers are ejected by ejector N.

Referring to Fig. 6, the sheet metal exterior of the cabinet supported by a frame comprising two horizontal channel bars 70 supported above the floor by legs 71 and 72 and plates 73, 74, 7'6 and 77 by a table '75 which supports also the punch press P. As shown in Figs. 1 and 19, a channel 7'0 supports angle bars 80 supporting a plate 81 which support rails 82 which support the workholders w comprising a plate 83 slidable along the rails and carrying resilient, condenser retainers 84. The workholders w are attached to links of a conveyor chain 85 which, as shown in Fig. 6, passes around a drive sprocket 86, a slack take-up sprocket 85a, upper idle sprockets 87, lower idle sprockets 38 and an end idle sprocket 89, all of these sprockets be ing supported by a channel bar 73. Referring to Fig. 11, sprocket 86 is supported by a shaft 98 journalled in bearings supported by the channels 78. To the shaft 90 there is attached a bevel gear 91 meshing with a bevel gear 92 connected with a shaft 93 supported by a bracket 94 attached to a bar 79. Shaft 93 is connected with a sprocket 95 connected by a chain 96 with a sprocket 97 attached to a shaft 117. Chain 96 passes around an idle sprocket 99 supported by a bracket 100 supported by plate 76.

The cabinet of the machine houses an electric motor, not shown, which is operatively connected in any suitable manner with a shaft 101 connected with a shaft 101a journaled in a bearing 101b supported by plate 74 (Fig. and connected with a sprocket 102 (also Fig. 7). A chain 103 passes around sprocket 182 and sprockets 104 and 105 and is engaged by an idle sprocket 106 pivotally supported at 107 by a lever 188 pivoted at 109 having a slot 110 through which passes a clamp screw 111 threaded into the plate 74. Lever 188 is adjusted to take up the slack in chain 183 and it is held in adjusted position by tightening the screw 111 which passes through a clamp washer 112.

Referring to Figs. 7 and 10, sprocket 184 is attached to the hub of a clutch driving member 115 of a onethird revolution clutch I having a driven member 116 keyed to the shaft 117, journaled in bearings 118 supported by a bushing 119 attached to plate 74. Shaft 117 carries the conveyor drive sprocket 97 (Fig. 11). Shaft 117 is journaled in a bearing 128 carried by a bracket 121 supported by plate 74. The hub of the clutch driving member 115 is fitted with bearings 122 which are journaled on the shaft 117.

Referring to Fig. 7, clutch driving member 115 is connected with clutch driven member 116 by lever 125 pivoted at 126 on member 116 and having a tooth 127 for engaging a notch 128 of the driving member 115. When the lever 125 is released for counterclockwise motion about its pivot 126, a spring 129, connecting lever 125 with member 116, causes the lever to connect the clutch members. Lever 125 is prevented from engaging its tooth 127 with a notch 128 by a lever 138 pivoted at 131 upon the plate 74 and urged counterclockwise by a spring 132 which surrounds a rod 133 and which is confined between the eye head 134 of the rod and a block 135 having a screw 136 pivoted on lever 138 and retained by a nut 137. The head 134 is pivoted at 138 on a lever 139 pivoted also on 131. Lever 139 has a notch 140 for receiving a latch pawl 141 attached to a shaft 142 which retains the lever 139 in the position shown against the action of a spring 143 connecting said lever with the plate 74. The right end of rod 133 is threaded to receive a nut 144 which, as shown in Fig. 7, is spaced slightly from the right side of the block 135. Nut 144 is locked in adjusted position by a lock nut 145. Lever 138 has a hook 146 for engaging a notch 147 in member 116. Member 116 supports a pivoted roller 148. To trip the clutch, the latch 141 is retracted by clockwise rotation of shaft 142 and the spring 143 pulls the lever 139 clockwise. Rod 133 moves left carrying with it the nut 144 which pulls on the block 135 and causes the lever 130 to move clockwise to pull the hook 146 out of the notch 147 and thereby allowing the lever 125 to move counterclockwise by the action of spring 129. The clutch members 115 and 116 are then connected and 116 will rotate counterclockwise. If there were but one set of parts numbered 138 through 146, the member 116 would turn one revolu tion. Toward the end of this movement, the roller 148 engages the lever 139 to move it counterclockwise against the action of spring 143 and to cause, through the action of the spring 132, the lever 130 to be forced counterclockwise against the periphery of member 116. Before the end of the one revolution the pawl 141 is per mitted to return by spring to be described to a latching position wherein the lever 139 will be latched as shown in Fig. 7 after the roller 148 passes to the right of it. Therefore, at the end of one revolution, the lever hook 146 will snap into the notch 147 to retain the plate 116 coincidentally with the retraction of the lever tooth 127 from a notch 128 of driving member 115. In order to obtain a partial revolution of the clutch before it is automatically thrown out, for example, one-third revolution, three sets of members, numbered 138 through 146, are provided and the parts of these sets are similar to those described marked with the same reference numerals. The numerals applying to one set have a prime affixed and the numerals applying to the other set have a double prime affixed. It will be seen that the locking levers 130, 130' and 138" are spaced equi-angularly about the driving member 115. If lever 139 is the first to be tripped, the clutch will rotate counterclockwise one-third revolution and roller 148 will pass under lever 139' to lift it so that it can be retained by lever 139 and will be caught by the latch 141' and the clutch member 116 will be stopped by the engagement with its notch 147 by the hook 146 of lever 13-8. For the next one-third revolution, the latch 141 is retracted so as to allow the clutch members to be connected for another one-third revolution during which the roller 148 will engage the lever 139" which will result in the en gagement by the member 116 with the hook 146 of lever 130".

The three latches 141, 141 and 141 are connected by shafts 142, 142' and 142", respectively, which, as shown in Fig. 8, are attached to levers 151, 151 and 151" connected by links 152, 152' and 152 with a plate 153 which, as shown in Fig. 10, is journaled on roller bearings 154 supported by the bushing 119. Plate 153 is urged by a spring 155 counterclockwise so that the shafts 142, 142' and 142 are urged clockwise in Fig. 8 or counterclockwise in Fig. 7 so as to urge the latching pawls into latching position. Plate 153 is rotated clockwise by a cam 156 engageable with a roller 57 carried by a lever 158 pivoted at 159 and connected with lever 153 by a link 160. Cam 158 is driven by a cam shaft 161 which, as shown in Fig. 9, is journaled in a bearing 162 supported by plate 74 and a bearing 163 supported by a bracket 164 attached to plate 74. Sprocket 185, which is journaled loosely on the shaft 161, is connected therewith through a one-revolution clutch K of the same construction as the clutch J except that there is only one set of parts like those numbered 138 through 146. The parts of clutch K, which are like those of clutch l, are indicated by the same numerals but with a triple prime aflixed.

The latch pawl 141" attached to shaft 142' is controlled by a pedal 165 (Fig. 20) pivoted at 166 connected by a link 167 with a lever 168 pivoted at 169 connected by a link 170 with a lever 171 attached to a shaft 172 connected with a lever 173 connected by a link 174 (Fig. 12) with a lever 175 pivoted at 176 and connected by a link 177 with a lever 178, (see also Fig. 8) connected with shaft 142'. Therefore, by depressing the pedal 165, the clutch K will be continuously tripped and cam shaft 161 will continuously rotate. Each time shaft 161 makes one revolution, clutch J is tripped but it automatically throws out at the end of one-third revolution so that the conveyor will be driven intermittently while the cam shaft rotates continuously until pedal 165 is released.

Figs. 20 and 21 show a bar 480 mounted on the upper end of a shaft 481 which is supported inabearing 482 attached to a cover plate 483 and in a bearing 484 provided by a plate 485. The bar 480 is held in a normal position by a spring 486 attached to the cover 483 and to a lever 487 attached to the shaft 481. Spring 486 urges lever 487 against a lever 488 on shaft 172. When pedal 165 is depressed, lever 488 on shaft 172 moves down (Fig. 22) and allows lever 487 on shaft 481 to move left (Fig. 22) or up (Fig. 23) by the action of spring 486 until the lever 487 strikes shoulder 488a of lever 488. This causes the pedal 165 to be held in depressed position so that the machine will operate until the operator at the left end of the machine moves the stopping lever 480 attached to shaft 481. So long as the pedal 165 is held down, the cam shaft 161 will turn one revolution and then stop; and while the cam shaft 161 is at rest, the conveyor B moves the workholders w a distance equal to the spacing of the workholders.
